What type of generator is needed to build a wind turbine which satisfy electricity demand of 700 kw per month Answered

First you need to wrap your head around the units. A watt is a flowrate, not a total amount. A watt for a period of time (such as watt-hour) is a total amount.

700kWh is 1kw for 700 hours, or 700 kw for 1 hour (or any other distrobution, 1 watt for 700,000 hours).

If you need 700kWh in a month, and there are an average of 30.4 days in a month, you need to generate 700kWh/30.42 == 23kWh per day. Assuming (unrealistically) that you could generate 24hrs/day you'd need to generate ~ 1kwh / h, or 1000 watts, all the time. You use a lot of electricity :)
